This patch does multiple enhancements to the way we build the Haddock
docs, motivated by the fact that if we don't run Haddock over test
files as well, bad formatting can be submitted and will accumulate
over time (without any checks).

The patch does:

- replace manual built ALL_APIDOC_HS_DIRS with automatically built one
  (from HS_DIRS)
- change Haddock so that it runs from the top directory (instead of
  from src/)
- change HsColour target file to be built via bash parameter
  substitution, rather than sed (I don't know how to do it in one go,
  so I use 2 intermediate variables)
- change 'hs-apidoc' target so that it depends on the real target
  file; in case no source file has been modified, running 'make
  hs-apidoc' twice will not result in two runs
- run HsColour/Haddock under en_US.UTF-8 locale, otherwise they can't
  parse correctly the Unicode chars in the test files

Additionally, wrong formatting (oops) in a test file has been
corrected.

This patch depends on “Option to include man pages in documentation”. In
the documentation build including man pages, all “:manpage:`…`”
references are converted to links. For man pages not provided by Ganeti,
Sphinx' standard formatting is used.

A small dance is necessary to hook into Sphinx' processing of man page
roles and to generate automatically resolved links. The code converts
“:manpage:`…`” for known man pages to the data structure equivalent of
“:doc:`$name($section) <man-$name>`”. Additionally it checks the section
numbers and formatting of references (in all builds).

Before this patch, HTML versions of man pages (man/*.rst) were already
built. However, since they are separate from the normal documentation,
their content is not indexed for Sphinx' search functionality.
Additionally it would simply be nice to have everything in one place.

To this end a new configure-time option is added to enable the inclusion
of man pages into the documentation. A dedicated option is necessary to
still be able to provide a static documentation build in the tarball
(not including man pages) as man pages contain build-specific paths and
values. The documentation with man pages is written to the directory
“doc/man-html”.

A future patch will extend Sphinx to link occurences of “:manpage:`…`”
to these man pages.

The first dot files we added way back in the 2.0 release are managed
manually: we build the .pngs ourselves, track them in .gitingore,
etc. Since then, we have switched to allow sphinx to build/manage them
itself, so it makes sense to cleanup the build system and covert
everything to this simpler method.

This patch simply converts from "image: x.png" to "graphviz: x.dot",
as an externally-referenced dot file, and removes all the custom
makefile rules for png conversion. The next patch will bring the
conversion further (by inlining then).

Additionally, while checking that the patch doesn't change the html
output, I saw that the use of "shape=diamond" with non-trivial labels
results in very ugly diagrams; so we split the question in such
decision boxes to make them more reasonably looking.

I don't remember why I introduced these when switching to pandoc, but
they are not absolutely needed. Instead of pre-generating them (which
might save some trivial cpu time), we can simply pass footer.rst as an
additional input file to pandoc.

The advantage in doing so is that semantic information is preserved;
when pre-generating and including them as-is, the entire structure is
lost, as pandoc won't reinterpret them, so things like a potential
table of contents will simply ignore the footer.

The patch also adds a new target to rebuild all man pages (both groff
and html formats), for testing changes to the pages easier.
